Patent number: 7892042Abstract: A connector is provided for terminating an end portion of a cable that includes a conductor. The connector includes a housing and a contact held by the housing. The contact is configured to be connected to the conductor of the cable. A keying member is rotatably held by the housing. The keying member is configured to cooperate with a keying element of a mating connector that mates with the connector. The keying member is movable about the housing such that the keying member is rotatably positioned to align with the keying element of the mating connector.Type: GrantFiled: July 15, 2009Date of Patent: February 22, 2011Assignee: Tyco Electronics CorporationInventors: Michael John Spicer, Daniel Eugene Stahl, Stephen Daniel Gherardini, Keith Edwin Miller, John Kevin Knoll

Another embodiment provides a method for expanding a jaw device at a treatment site and delivering a therapeutic agent. Another embodiment includes a catheter having an expandable member with hollow needles disposed on the outer surface of the expandable member. Yet another embodiment provides a method for expanding the expandable member at a treatment site and delivering a therapeutic agent into the tissue.Type: GrantFiled: May 10, 2004Date of Patent: July 13, 2010Assignee: Medtronic Vascular, Inc.Inventors: Marvin J.

Publication number: 20040240684Abstract: The invention disclosed is a room volume control that simultaneously and automatically controls both the loudness and the loudness compensation of sound from speakers of an audio system as the volume level is changed. A resistive volume control having a movable contact provides a different resistor value from an input terminal of the volume control to the movable contact for controlling the loudness of an audio signal. A parallel circuit of an inductor and a capacitor coupled through the movable contact is in series with the resistor value of the resistive volume control from the input terminal to the movable contact for controlling the loudness compensation of the audio signal.Type: ApplicationFiled: May 29, 2003Publication date: December 2, 2004Inventors: Mark Cerasuolo, Kevin Knoll
